Mahiru Shirota

Mahiru Shirota (城田真昼 Shirota Mahiru) is the protagonist of Servamp. He is the Eve of Sleepy Ash, the Servamp of Sloth. He is a first year high school student who greatly likes simple things and dislikes complicated things.

Appearance
Mahiru is an adolescent male with short, light brown hair that frames his face. He also has large brown eyes.

Typically, Mahiru can be seen wearing a brown shirt with a white collar. Over his shirt he wears an orange jacket, with his sleeves slightly rolled up. Around his neck, he wears a red tie. In this outfit, Mahiru also wears beige pants that end just below his knees. His sneakers are white and orange.

In illustrations, he’s often seen wearing orange, but apart from that he has a wide range of taste. He mostly opts for comfortable clothes, but he does have formal attire, such as a tie and a vest.

Occasionally, he wears the black and white striped wristband Sakuya gave him.

Personality
Mahiru is open-minded and independent. He’s not afraid to show what he’s truly feeling or thinking, so he can be critical of other people. Mahiru prefers simplicity over difficulty, therefore he behaves quite responsibly. He depends on himself instead of turning to someone else for help, most likely because he never felt the need to rely on others before.

He has a small amount of patience, typically raising his voice when he's irritated or annoyed. He often takes the role as the ‘mother hen’ because he tends to act more mature than his friends or those around him.

However, Mahiru knows how to use his words wisely for encouragement, almost always knowing exactly what to say and what not to say. As soon as he sets his eyes on a goal, he won’t change his mind, doing anything in his power to achieve that goal.

Past
Mahiru's mother died at a very young age. There was no mention of his father, and he didn't have any close family members to take care of him. His uncle, Toru Shirota, decided to take him in and raised Mahiru himself. However, his uncle was very busy and had to spend days away from home because of his work. Mahiru grew up alone and took care of himself. Because of this, he taught himself basic housework, such as cooking, cleaning, and sewing.

Meeting Kuro
On his way home from school, Mahiru finds a black cat laying exhausted on street and cannot move due to the heat so decides to take the cat home, giving him a bell and named him Kuro due to its black fur. However, the next day, Mahiru discovers there's a stranger eating and watching TV in his apartment, prompting him to attack the stranger, which the latter easily dodged. When Mahiru opens the curtain, exposing the young man to sunlight, the man changed into Kuro, which Mahiru confirms again when he closed the curtain, changing Kuro back into the stranger before, revealing the Kuro and the stranger are the one and the same. Mahiru questions what he is, which Kuro answers that he is a vampire. Mahiru questions is Kuro the street slasher who has attacked several people he had recently heard and thought Kuro want to suck his blood and kill him, but Kuro denies, not wanting to drink blood of people like Mahiru. Kuro agrees to leave once it was dark and tells Mahiru he must not call him by his name while he is in his human form. However, mistaking what Kuro meant by name, Mahiru calls him with the name he gave to him, accidentally forming a temporary contract with the vampire and they cannot be separated until the contract is cancelled within 24 hours as long as Kuro doesn't drink Mahiru's blood within the time limit. While shopping, Mahiru and his friends are attacked by another vampire, Belkia. Mahiru tries to convince Kuro to fight, but Kuro refuses, angering Mahiru who tells him to run alone while he tries to help his friends. Mahiru's action urges Kuro to protect him. Refusing to leave Kuro alone, Mahiru decides to finalise their contract by making Kuro drink his blood, making Mahiru Kuro's master or Eve and giving Kuro the necessary power to defeat Belkia. Before Kuro could kill Belkia by drinking his blood, Mahiru stops him, reminding Kuro of his own words that he as the Eve will take all responsibility so Kuro must listen to him, making Kuro to spare Belkia. The vampire reveals that he attacked them under the order of another vampire named Tsubaki who hates Kuro. Shortly afterwards, Mahiru and Kuro lost consciousness, exhausted from the fight.

Encounter with Tsubaki
Awakened the next day in his room, Mahiru contemplates what happened was a dream, which was proven wrong when Kuro talks. Mahiru quickly goes to school and asks Sakuya what happened to Ryusei. When Sakuya made a dejected face, Mahiru thinks that Ryusei didn't make it until the said person arrives. This angered Mahiru who thinks the worst happened and punishes Sakuya as the result. However, Mahiru finds out that Ryusei didn't remember what truly happened yesterday and thinks that the wound he received was from an accident. On his way back home, Mahiru questions Belkia about Tsubaki, only for the vampire in question to appear himself, retrieving Belkia. Tsubaki introduces himself as the eighth Servamp and Kuro's youngest sibling, something that Kuro doubts since he never heard of any Servamp named Tsubaki. Mahiru then questions Tsubaki's intention and protests that he shouldn't be involving innocent people. This only annoys Tsubaki who thinks they are involved, especially Kuro, and proceeds to attack the Servamp. Mahiru tells Kuro to drink his blood, but Kuro refuses because he is still exhausted from the fight yesterday, spitting out Mahiru's blood when the Eve tries to force him to drink. As Tsubaki attacks them again, Mahiru feels a familiar feeling from Tsubaki that he experienced before and decides to make the vampire face him by giving him a name. However, before Mahiru can do so, Tsubaki attacks him, but he and Kuro are saved by another Servamp, All of Love, who moved them to the other side of station and left the two with his e-mail address.

Alliance with Misono and Snow Lily
At school, Mahiru receives e-mail from All of Love. Just as he received the e-mail, he and Kuro are abducted by All of Love's Eve, Misono Alicein who came with All of Love's twin subclasses. At Alicein mansion, Mahiru is introduced to All of Love who now goes by the name Snow Lily, and the Lust Pair demands Mahiru to give Kuro to them so they can defeat Tsubaki. Mahiru and Kuro escapes to a room filled with children, and Mahiru at first mistakes the children as Lily's children, but Lily explained all of them are his subclasses and two of his subclasses were killed by Tsubaki a few days before. Misono then explains his reason to fight to protect those he cares for, a reason that Mahiru able to relate. Mahiru offers Misono to form an alliance instead of fighting alone, an offer that Misono accepts.

Servamp Meeting
Mahiru and Kuro goes to a meeting between Servamps at a nearby family restaurant. There, he meets The Mother of Wrath, World End of Gluttony, and Doubt Doubt of Envy. The discussion goes nowhere as the vampires gets distracted by their own stories and problems, enraging Mahiru who tells them to focus on their current problem regarding Tsubaki and all of them must do something. Mahiru's disposition leads the vampires to point Mahiru as the leader and the one responsible in gathering all seven Servamps. To do this, Kuro must give him a weapon called Lead for Mahiru to fight. Under Kuro's instruction, Mahiru enters Kuro's mind where he is greeted by a Black Cat who tells him to choose his presents. Assuming the present means weapon, Mahiru chooses the simplest looking present and it changes into a broom. Kuro reminds Mahiru that when they first met, Mahiru attacked him with a mop, asking Mahiru does he thinks cleaning tool equals a weapon, which Mahiru denies. Due to their noisiness, they got kicked out from the restaurant.

Battle Against Sakuya, Belkia, and Otogiri
Mahiru hears that Sakuya hasn't come to school for the past few days. Worrying about his best friend, Mahiru decides to visit Sakuya and give him a snack and box lunch. On his way to Sakuya's house, Mahiru starts to have difficulty in remembering Sakuya to the point forgetting who Sakuya is for a second until Sakuya himself approaches him. He is then lured into an empty alley way where he and Kuro are tied by strings. To Mahiru's shock and disbelief, Sakuya reveals himself to be one of Tsubaki's subclass like Belkia. Sakuya accuses Mahiru of not believing in him as friends, so Mahiru tries to explain that he didn't tell anything because he doesn't want to get Sakuya involved, but Sakuya won't hear any of it and attacks him, which blocked by Kuro. Mahiru tells Kuro to drink his blood, but Kuro refuses because it was pointless since Mahiru is unsure whether he wants to protect or fighting Sakuya. Mahiru and Kuro are saved by Misono and Lily, the two able to defeat Belkia. However, Sakuya tricks Misono to let his guard down by using his friendship with Mahiru, which successfully made Misono hesitated and Sakuya uses the opportunity to attacks Misono, injuring him. Enraged at Sakuya for injuring Misono through deception, Mahiru finally decides to fight. Kuro tries to convince Mahiru to escape since Mahiru is still unsure, but Mahiru refuses, feeling guilty for Misono who was protecting him yet he did nothing. Mahiru attacks Sakuya, but as he did so, he becomes afraid and feels that he is not the one who moves his Lead around. Mahiru's uncertainty overflows inside Kuro, causing the Servamp to lose control of his power and tries to engulf Mahiru. As he becomes afraid and almost get engulf, Sakuya tries to help him, revealing that he attacked and taunted him because he wants to die by Mahiru's hands. Before Mahiru can take Sakuya's hand, Doubt Doubt and his Eve arrives, stopping Kuro's rampage and chased away the Subclasses. Mahiru questions Sakuya about his earlier statement, but Sakuya simply gives him back the wristband that he bought for him. Misono's servant, Dodo, arrives to take Misono to hospital and Lily also offers Mahiru to go as well, but Mahiru declines since his wound is not severe. Doubt Doubt's Eve, an antique dealer, then tells Mahiru that he should have killed Sakuya while he can since Sakuya himself wants it. He explains to Mahiru that if the Eve begins to fear the Servamp's power, then the Servamp will gobble him up whole, shocking Mahiru. He then offers Mahiru a chance to nullify the contract between him and Kuro if he is regretting for ever picking up Kuro and then Mahiru can return to his normal life.

Sakuya's Past
The next day, Mahiru contemplates of what it means to wield a power. He doesn't regret picking up Kuro and became his Eve, but is confused because the power he received is different from what he had thought. His thoughts is interrupted when he heard his uncle came home and attacks Kuro whom he thought was a burglar until Mahiru calms him down and introduced Kuro, changing into his cat form, and asks for his permission to keep him. His uncle then takes him to a sushi shop to dinner, coincidently meeting Tsubaki who proceeds to reveal Sakuya's past and sneers Mahiru for not understanding Sakuya even though they are friends. When Tsubaki is leaving, Mahiru wanted to tell Tsubaki to free Sakuya, but couldn't bring himself to say so. Mahiru starts to scolds himself for his inability to understand Sakuya and feels guilty for lying to him without considering his feeling. Mahiru's uncle comforts him, telling Mahiru that if he feels that way, he should set things right again with his friend. At the school festival, Mahiru directly confronts Sakuya and chases after him until they reaches the rooftop. Sakuya refuses to apologize for what he did and persists he is an enemy, but Mahiru insists they are friends and despite most of his memories being a fake, the one whole year he spent times with Sakuya was so much fun. Sakuya states he is not human and then let himself fell from the rooftop. Mahiru catches Sakuya as he tells him that it doesn't matter if he is a vampire because he has the power to take his hand. Mahiru summons his broom and use it to fly to the nearby backyard where he finally reconciles with Sakuya and promises he will stop Tsubaki so Sakuya can be free, which Sakuya is grateful of. Mahiru then tells Kuro that he seriously wants to stop Tsubaki so he needs to become stronger.

Meeting Mikuni and Jeje
A month since Mahiru made contract with Kuro, Mahiru trains himself and demands Kuro to do the same instead of playing game, stating what's important to him are friendship, effort, and victory. Remembering what happened last time when Kuro lost control, Mahiru apologise to Kuro and once again affirms his desire to become strong. Mahiru then notices that Kuro never drink his blood other than when they're fighting and instead eats normal foods. Mahiru tells Kuro that he can drink his blood if he wants to, but Kuro declines because he doesn't want to drink it, confusing Mahiru. Kuro and Mahiru then tries to open the vampire SNS, only to find the website has been closed down. Mahiru asks Lily about this, but Lily himself doesn't know the cause.

On their way home, Mahiru and Kuro once again meet with Doubt Doubt and his Eve who are chasing a subclass and killed him. The sight horrified Mahiru, telling the antique dealer that he doesn't need to kill the vampire, but the antique dealer retorts it's normal to kill their enemies. Seeing how knowledgable the antique dealer is regarding vampires and know that he is actually a nice person since he saved them, Mahiru begs him to teach him how to properly use his Lead, shocking the antique dealer and Kuro. The antique dealer then introduces himself as Mikuni Alicein, Misono's older brother, shocking Mahiru and Kuro. They continues their talk at a nearby restaurant where Mikuni reveals his reason to help them: first is because Kuro is the strongest Servamp and to find out Tsubaki's goal. Mahiru reminds Mikuni that Tsubaki's goal is to start a war, but Mikuni points out that they don't know why he wants to start a war in the first place. This reminds Mahiru when Tsubaki mentions he is trying to lure something. Mikuni then explains that the vampire SNS was maintained by an institution. The mention of the institution surprised and made Kuro uneasy, something that Mahiru notices. Mikuni then asks does Mahiru won't annul the contract he made wit Kuro, something that Mahiru confirms because he is able to reach Sakuya's feeling thanks to what happened. Mahiru determines to become stronger so he and Kuro can become real partners. Together with Lily and Doubt Doubt whose current name is Jeje, Mikuni agrees to train Mahiru.

Meeting Tetsu and Hugh
While at school, Mahiru and Kuro overhears someone talking about Kuro and he tries to follow that person, who is revealed to be his senior, Shuhei Tsuyuki. Helping him after he fell from stair, Mahiru straightforwardly asks him is he a vampire, angering Shuhei who then forces Mahiru to help in the summer festival. After helping in the festival, Mahiru tells Kuro about his mistake regarding Shuhei, and Kuro tells him that getting suspicious of someone isn't like him at all and he is fine the way he is now, though the vampire quickly takes back the last statement so Mahiru will stop doing reckless thing. Mahiru is then approached by a man who claims to found a case and asks Mahiru to take it to the lost and found stall. On his way to the stall, he meets a young man who is looking for something so Mahiru offers his help to look for it. When Mahiru asks what did he lost, the man answers that he is looking for a coffin with a vampire inside. This shocked Mahiru who doesn't know what to say considering his mistake when asked Shuhei. They are interrupted by an explosion that comes from a similar silver case that Mahiru is carrying. Mahiru at first hesitated to call Kuro due to the man's presence, but then remembers Kuro's words so he decides to believe that the man is a good person and calls Kuro, who takes him to the sky so the bomb will explode without any casualty. However, Kuro threw the bomb ten seconds earlier and the bomb falls down again. The young man from before, however, placed the bomb inside his coffin where it explodes safely without destroying the coffin. The man introduces himself as Tetsu Sendagaya, the son of the owner of hot spring inn and the Eve of Servamp of Pride, Old Child.

Training
Mahiru takes the Pride Pair back to his apartment where they continue their discussion. Old Child, reintroducing himself with his current name Hugh, states that he has been looking for Kuro to talk regarding Tsubaki and he and Tetsu agrees to work together with them. Happy that they gain a new ally, Mahiru invites Tetsu and Hugh to his training with Mikuni, Jeje, and Lily. Meeting Mikuni at the park, Mikuni tasked them to remove all of Jeje's paper bags from his head as their first training stage. Hugh and Kuro are busy playing, leaving only Mahiru and Tetsu to train. Mahiru makes his first move, which Jeje easily dodges since Mahiru still can't properly control his Lead. Mahiru wonders why his Lead is a broom, and Mikuni explains that Lead takes the shape of an item that Eve can tie down their vampire the best with. Disagreement then occurs between Hugh and Mikuni regarding the position between vampires and humans, but Mahiru states that he doesn't really care about their opinion because they can think objectively and his partner is Kuro, so if it's about Servamp like him, he wants to hear it from Kuro himself and not someone else. Mahiru asks Kuro of his opinion, but Kuro feels it's too much to handle. Mahiru's answer impresses Hugh who takes a liking to him and willing to bet everything on him. Their training ends with Tetsu using his full power to attack Jeje, blowing the paper bags from his head and everyone around them, including Mahiru and Kuro. Mikuni quickly covers Jeje's face with his hat as he concludes their first training. Mahiru is amazed by Tetsu's strength and looking forward to fight together with them all including Misono. The next night, Mahiru invited Misono to train as well, but the moment he mentions that Mikuni is the one who trains them and when the said person arrives, Misono quickly attacks his older brother, confusing Mahiru who then tries to stop Misono and questions his sudden hostility. Misono angrily scolds Mahiru for easily trusting people, but Mahiru defends himself by revealing that he thinks Mikuni is telling the truth because the older man has collection of his photo, much to Misono's annoyance. Jeje knocks Misono unconscious and Mikuni decides to cancel their training plan. Mikuni gives Mahiru one last advice before leaving wit Jeje. Since the training is cancelled, Mahiru and the others decided to continue their discussion at a nearby restaurant. Mahiru contemplates to ask the neutral organization, C3, for help, but Hugh objects the idea since C3 is not as neutral as it claims but a self-serving organization. Hugh warns Mahiru that getting involves with C3 will only bring trouble and reminds his siblings not to repeat their mistake. Mahiru inquires what this mistake they are talking about. Lily tries to explain that it happened when they received a certain order from C3 long ago, but Kuro interrupted them before it can continue further, surprising Mahiru. Hugh and Lily shifts the subject to the bombings caused by Tsubaki since three days ago, revealing that one of the places that got bombed was Mahiru's school. Mahiru was horrified when he saw his school destroyed, wondering what exactly is Tsubaki's goal. He asks Kuro about this, but is then knocked unconscious by two girls working for C3.

Sleepy Ash
At first, he found Kuro to be lazy and messy, always yelling at him whenever he left crumbs on the floor and the first time they met, he hit Kuro with a broom. But, later on in the chapters, they seem to get closer. After every fight they encounter, the first thing he does is ask Kuro if he is okay. Also, when Kuro mentioned he liked ramen, Mahiru took note of this and bought him packets of ramen and other types of food. When Kuro asked him if he was ever sorry he found him, Mahiru said that he could never, ever regret finding him. Also, when Mikuni asked if he wanted to break the bond between him and Kuro, Mahiru immediately rejected the idea, yelling at him that he wants to be Kuro's equal partner and toughen up. He does not want to decide his and Kuro's fates and choices alone, wanting only himself and Kuro to decide because they are partners, nobody else. He trusts Kuro with his life. When Mahiru suggested if they could get the help of C3, Kuro yelled that they didn't need them. This instantly made Mahiru worried because Kuro doesn't normally yell like that. When they were captured by the C3, Mahiru instantly called out for Kuro when he awoke. Mahiru kept rejecting the offer of helping out C3 to capture Tsubaki, saying that he won't decide without Kuro's consent. He used a dangerous amount of energy trying to escape and when he was reunited with Kuro, the first thing he asked him is if he was alright. Then, they both had a talk with each other, Mahiru asking if Kuro was keeping any secrets from him. Kuro responded that he is but can't tell him cause it may get him killed. He surprised Kuro by telling him that he doesn't need to tell him, saying that he trusts him and to not forget that he will always be beside him, that they are partners, making Kuro secretly happy. Over all, Mahiru cares a lot about Kuro and his well-being and trusts him more than anyone else and wants to become great friends.

Sakuya
Sakuya is Mahiru's best friend, both always hung out together after school with their other two friends. Even after Sakuya is revealed to be Tsubaki's subclass and has been manipulating his memories about being childhood friends while in fact they only knew each other for a year, Mahiru still considers Sakuya as a friend. This feeling grew stronger once Mahiru knows Sakuya's past and his true feeling, making him determined to stop Tsubaki so Sakuya can be freed. Sakura initially only befriends Mahiru out of boredom, but grew to cherish their friendship more than his loyalty for Tsubaki. Their friendship became stronger after Mahiru reaches out to Sakuya and vows to free him, making Sakuya glad and grateful for Mahiru for finding him.

Misono Alicein
When they first met, Misono wanted to take Kuro away from him, giving a bad impression to Mahiru. After knowing Misono's reason to fight, Mahiru decides to help him since is able to relate with his feeling of wanting to protect those whoa re important to them. Misono was very happy when Mahiru offers to become his friend since it was the first time someone willing to become his friend, which he usually hides out of embarrassment. It doesn't take long time for Misono to become protective of his first friend, saving Mahiru when he was attacked by Tsubaki's subclasses, risking his life to do so. Mahiru's friendliness and open minded personality quickly made him understood how nice Misono actually is despite his outward trait and regards Misono as one of his close friends, worrying about his weak body and will help him if he is in trouble. Even though Misono doesn't interact well with others and has a grumpy personality, Mahiru and Misono overall are good friends.

Mikuni Alicein
Mahiru's first impression on Mikuni is that the older man is a weird person due to his fondness for his doll and gets annoyed whenever the man accuses him of staring at his doll or Misono with lewd eyes. They also have a contradicting view regarding how they deal with their enemies; while Mahiru objects to kill his enemies, Mikuni thinks it's necessary to kill them. Despite their difference, Mahiru doesn't think badly of Mikuni since he saved him and Mikuni quickly became a mentor to Mahiru, helping him train his powers to work well with Kuro. Even after being told by Misono not to trust him, Mahiru still respects Mikuni and trusts him to a certain degree. Mikuni views Mahiru as a naive boy, but doesn't hate him for it since the boy befriends his younger brother.
